Overview

The Monoprice 2-Channel A/B Speaker Selector solves a common home audio problem: you have one or two audio sources and want to send sound to speakers in different rooms or zones without buying a multi-zone receiver. It accepts two stereo inputs and routes them to two separate speaker outputs, with independent volume knobs for each zone. If you want music in the living room and kitchen from the same amplifier but at different volumes, this is the simplest way to make that happen. It requires no power source — it's a passive switching and attenuation box that sits between your amp and your speakers.

The build is functional and compact, with a straightforward front panel featuring the A/B source selector and two volume dials. On the back, bare wire terminals accept speaker cable up to 14AWG gauge, which covers the vast majority of home speaker wire. There are no banana plug jacks, so you'll need to strip and insert wire directly. The 100 watts per channel rating is adequate for most home stereo and bookshelf speaker setups, though users with high-output amplifiers or power-hungry floor-standing speakers should verify their system stays within that limit. It's a budget-friendly, purpose-built tool that does one job well without overcomplicating the setup.

Pros & Cons

👍 Pros

  • Independent volume controls for each speaker zone let you balance audio between rooms without touching the receiver
  • Simple passive design requires no power supply — just wire it in and it works
  • Supports up to 100 watts per channel, which handles most home stereo setups comfortably
  • Accepts two stereo inputs, so you can switch between or distribute multiple audio sources without re-cabling

👎 Cons

  • Bare wire terminals only — no banana plug or spade lug connections, which makes setup less convenient
  • 100 watts per channel ceiling may be limiting for users with higher-powered amplifiers or demanding speaker loads
  • Only supports two output zones, so expanding beyond two rooms requires additional selectors or a different solution
  • Build quality is basic and utilitarian — the plastic housing won't win any aesthetic awards in a visible equipment rack

Frequently Asked Questions

Yes. The 2-Channel A/B selector lets you distribute two stereo audio sources to two separate speaker destinations. You can switch between sources for each zone or run both simultaneously, giving you flexibility in a multi-room or multi-source setup.
It uses bare speaker wire terminals that accept wire gauges up to 14AWG. There are no banana plug or spade lug connectors — you'll strip your speaker wire and secure it directly into the binding posts.
The selector supports up to 100 watts per channel, which covers most home stereo amplifiers and AV receivers. If your amp outputs more than 100 watts per channel, this unit may not be appropriate and could be a limiting factor.
Yes. Each output zone has its own independent volume knob, so you can set different volume levels for different rooms or speaker pairs without affecting the other zone.
For typical home audio use, the signal path through the selector is passive and straightforward. At normal listening volumes with standard home speakers, most users won't detect meaningful degradation compared to a direct connection.
